 desc = "The remote host is missing an update to ethereal
announced via advisory DSA 324-1.

Several of the packet dissectors in ethereal contain string handling
bugs which could be exploited using a maliciously crafted packet to
cause ethereal to consume excessive amounts of memory, crash, or
execute arbitrary code.

These vulnerabilites were announced in the following Ethereal security
advisory:

http://www.ethereal.com/appnotes/enpa-sa-00010.html

Ethereal 0.9.4 in Debian 3.0 (woody) is affected by most of the
problems described in the advisory, including:

* The DCERPC dissector could try to allocate too much memory
while trying to decode an NDR string.
* Bad IPv4 or IPv6 prefix lengths could cause an overflow in the
OSI dissector.
* The tvb_get_nstringz0() routine incorrectly handled a
zero-length buffer size.
* The BGP, WTP, DNS, 802.11, ISAKMP, WSP, CLNP, and ISIS
dissectors handled strings improperly.

The following problems do NOT affect this version:

* The SPNEGO dissector could segfault while parsing an invalid
ASN.1 value.
* The RMI dissector handled strings improperly

as these modules are not present.

For the stable distribution (woody) these problems have been fixed in
version 0.9.4-1woody5.

The old stable distribution (potato) these problems will be fixed in a
future advisory.

For the unstable distribution (sid) these problems are fixed in
version 0.9.13-1.

We recommend that you update your ethereal package.
